DAVID O. FRANKLIN, 0F CARLISLE, INDIANA.

REFRIGERATOR.

f0 all whom it may concern:

Be it known that I, DAVID O. FRANKLIN, a citizen of the United States,and a resident of Carlisle, in the county of Sullivan and State ofIndiana, have invented certain new and useful Improvements inRefrigerators, of which the following is a full and completespecification. I

My invention relates to refrigerators of the class that is mounted inwells or cisterns to take advantage of the cool air contained therein;and it has for its object the provision of means by which the airadmitted to the cooling chamber is drawn from the region adjacent to thesurface'of the water to insure purity and coolness thereof.

My invention will be described in detail 2 hereinafter and illustratedin the accomcistern, showing my improved refrigerator 1 in positiontherein, the refrigerator-casing being shown in section; Fig. 2, a frontView of the refrlgeratlng-chamber; F 1g. 3, and Fig. 4, vertlcalsectional vlews of the chamber looking in opposite directions; Fig. 5, av

top plan view of the chamber; Fig. 6, a bottom plan view; Fig. 7, a topplan view of the casing extended into the well or cistern; Fig. 8, anedge view of one of the doors, and Fig. 9, a view in perspective of thepart of the casing extended into the'well or cistern.

In the drawings similar reference characters indicate correspondingparts throughout all of the views. I

A indicates a well orcistern over which is secured a cover or floor B,having anopening C. S

The casing of my improved refrigerator consists of the casing 1, securedover the opening C and preferably made rectangular in cross-section, andhaving the ventilating openings 2 in its upper end covered with a screenfabric.

3 indicates the casing extended down into the well from the underside ofthe cover B in alinement with casing 1, said casing 3 being rectangularat the top and bottom and swelling outwardly in its middle, as shown at4, where it is circular, its diameter being substantially equal. to thelength of the diagonal of the rectangular ends. The purpose of formingcasing 3 bulged, as described, is to form a space for the passage ofcold air around the refrigerator when Specification of Letters Patent.Patented June 2'7, 1911.

lowered into the tube, as hereinafter described.

5 indicates braces secured to the lower end of the casing 3 and extendedupwardly to engage the side walls of the well or cistern to brace thelower end of the casing to prevent it from swinging when in position.

6 indicates angular vertical guides conneoting opposite corners of theupper and lower ends of the casing 3.

7 indicates a tube secured adjacent to the lower end of casing 3 andextended to the center thereof, 8 a flexible tube secured to tube 7 9 afloat having an opening 10 therein covered with screen fabric 11, thefree end of flexible tube 8 being extended down into the water andsecured in the opening 10 of the float. The tube 8 must be of suflicientlength to reach the water in the well or cistern, however low it mayfall, and to prevent the tube from floating and endangering theoperation of the float and tube I provide a weight 12 that is suspendedfrom a roller 13 that rides on the tube 8.

It will be understood from this construction that the fresh and cooledair will be constantly supplied to the casings 1 and 3, which, as it iswarmed, will rise and pass out through the ventilating-openings 2, sothat anything that may be placed in said casings will be kept cool bycontacting with the air.

14 indicates the refrigerating-chamber, consisting of a rectangular boxslidably mounted in casing 1 and on angular guides 6, said box havingsupporting-arms 15 secured to its top, to which a rope 16 is fastened,and running over pulleys 17 and 18, secured in the top and to the sideof the easing 1, respectively, is wound upon a windlass 19, operated bycrank-shaft 20 and gearing 21. The box 14 is divided into a num ber ofcompartments 22, by means of horizontal partitions 23, and eachcompartment is closed by a separate sliding door 24, mounted in groovedguides 25, to hermetically seal each separate compartment to prevent theodors of the contents of the several compartments from intermingling andspoiling the taste of such articles as butter and milk with the odors ofraw and cooked meats and vegetables. I

By lowering the box 14 into casing 3 it will be apparent that it will bechilled by radiation of the heat therefrom, but to more quicklyaccomplish refrigeration I provide an opening 26 in the bottom of thebox and extending into the lowermost compartment 22 and a tube 27extending from the bottom to and through each of the horizontalpartitions 23 and a tube 28 from the top of the box downwardly to andthrough each partition 23 and a hole 29 in the top and extending intothe topmost compartment. As the hole 26 and tubes 27 are on one side ofthe box and the tubes 28 and hole 29 on the other side thereof, it willbe apparent that each compartment is separately ventilated, the airpassing into it on one side and, crossing the compartment, passes outthrough the other side, and its contents are quickly chilled, as well asventilated.

The lower end of the box 1% is formed with a depending flange 30 toinsure a passage under the box for air when the box is in its lowermostposition, said flange being formed with a notch 31 to receive tube 7when lowered.

32 indicates a door on the side of easing 1, admitting to the interiorof the casing, so that access may be had to the contents of the box 14,said door being formed with an oiiset 33 to throw the door out of linewith the sliding doors 24 to open and close the refrigeratingcompartments.

Having thus described my invention, what I claim is l. A refrigeratorcomprising, in combination with a well, a casing seated in and over thewell, the part of the casing within the well bulged intermediate of itsends a refrigerating-chamber slidably mounted in said casing, afloatresting on the water in the well, and a tube connecting the float andthe lower end of the casing, substantially as shown and described.

2. A refrigerator comprising in combination with a well, a casing seatedin and over the well, the part of the casing within the well bulgedintermediate of its ends, and a refrigerating chamber slidably mountedin said casing, said casing being provided with ventilating-openings,substantially as shown and described.

3. A refrigerator comprising in combination with a well, a casing seatedin and over the well, the part of the casing within the well bulgedintermediate of its ends, angular vertical guides secured in the bulgedportion of the casing, and a refrigerating-chamber slidably mounted insaid casing and in said angular guides, the casing being provided withventilating-openings, substantially as shown and described.

4:. A refrigerator comprising, in combination with a well, a casingseated in and over the well, a refrigerating-elmmber slidably mounted insaid casing, a float resting on the water in the well, a tube connectingthe float and the lower end of the casing and a weight normally mountedon the tube, substantially as shown and described.

5. A refrigerator comprising, in combination with a well, a casingseated over the well, a casing extended into the well, thelast-mentioned casing being rectangular at its upper and lower ends andits middle bulged and circular in section, angular guides secured insaid bulged casing, and a refrigerating-box slidably mounted in saidcasings and engaging said angular guides, substantially as shown anddescribed.

6. A cooling device for well-refrigerators comprising in combinationwith a casing extended into the well, a tube secured to the lower end ofthe casing, a float secured to the said tube, a roller mounted on saidtube, and a weight suspended from said roller, substantially as shownand described.

In witness whereof, I have hereunto set my hand in presence of twosubscribing witnesses.

DAVID O. FRANKLIN.
